The structuring

<a href="write_image.html"><code><span data-if="hdevelop" style="display:inline">write_image</span><span data-if="c" style="display:none">write_image</span><span data-if="cpp" style="display:none">WriteImage</span><span data-if="com" style="display:none">WriteImage</span><span data-if="dotnet" style="display:none">WriteImage</span><span data-if="python" style="display:none">write_image</span></code></a>.  However, take care to use an image format that
supports alpha channels to save the shape of the structuring element
such as 'tiff', 'jp2' or 'png'.  These files can then be loaded
again with 该算子 <a href="read_image.html"><code><span data-if="hdevelop" style="display:inline">read_image</span><span data-if="c" style="display:none">read_image</span><span data-if="cpp" style="display:none">ReadImage</span><span data-if="com" style="display:none">ReadImage</span><span data-if="dotnet" style="display:none">ReadImage</span><span data-if="python" style="display:none">read_image</span></code></a>.</p>
